Ma i/V72? LZO/I/ JAM As Patented Nov. 22 1932 UNITED STATES PATENT OFFICE LEON SAIVES, OF BILLANCOURT, FRANCE, ASSIGNOR TO LOUIS RENAULT, OF

BILLANCOURT, FRANCE METALLIC FLOORING AND METHOD OF LAYING THE SAME Application filed March 28, 1929, Serial No. 350,724, and in France April 6, 1928.

The present invention relates to improvements in the manufacture of the flooring plates, of the class embodied in my United States Patent No. 1,686,106 dated October The said improvements relate to the construction of the unit plates which make up the flooring, and also to the methods by which the said plates are employed and assembled.

The accompanying diagrammatic drawing shows the improved arrangement.

Fig. 1 shows four unit plates connected together at a common angle.

Fig. 2 relates to a modification.

Fig. 3 shows a panel which consists of a certain number of the unit plates which are preliminarily assembled and can thus be laid as a single device upon the floor.

Fig. 4: is a vertical section taken through one assembly of the unit plates, and showing a tubular rivet.

As specified in the aforesaid patent, each unit plate 1, preferably of a square shape, is pressed into an inverted concave form, the

corners being bent down so as to offer the small sides 3, which are connected by a sunken part 4 with the main portion of the unit plate.

The ribs 2, which are given a circular shape in the aforesaid patent, are formed in the present structure by the use of parallel lines having rectilinear directions, and they may form a geometrically straight line or may consist of a straight assemblage of small sinuous curves. The direction of the said ribs is variable from one unit plate to another, and Figure 1 shows ribs 2 which are straight and are parallel to the sides of the unit plates 1, said ribs being situated in two I perpendicular directions, the direction in one unit plate being different from the direction in the adjacent plate.

In Figure 2, the ribs 2 are also straight, but they are now parallel to the diagonals of the plate, their direction varying from one plate to the next.

Obviously, the said ribs might be situated in other directions, provided the ribs on one plate alternate in direction with the ribs on the adjacent plate.

The said unit plates are assembled together, as in the aforesaid patent, by fitting, between two pressed concave members, the set of sunken parts 4 situated at the four respective adjacent corners, the whole being secured at this point by bolting or by like means.

An additional improvement consists in piercing each unit plate with one or more holes 12 through which cement is supplied below each metallic plate.

The flooring consisting of such plates may be laid upon a bed of cement and sand, then supplying cement under pressure through apertures 12, so that the whole will be bound together. In this case, it is not necessary to pierce holes in each plate.

- The present invention further relates to a somewhat simplified method of laying the said plates, said method including the preliminary step of connecting a plurality of the plates into the form of a panel. 3

Fig. 3 represents such a panel, which com prises 12 of the said unit plates, and this panel is laid upon the floor as a single piece. In the preparation of such panels, instead of the bolts placed at the point common to the four corners of adjacent plates, I now employ rivets which may be solid or tubular. In this latter case, the tubular rivets may be optionally used to permit the introduction of the cement therethrough.

As shown-in the sectional view, Fig. 4, the square space which is formed between the four plates meeting at a given angle, is adapted to receive the device consisting of two pressed sheet metal concave members 5 and 6. One of the said members 5 fits into the said space, since its flanged edges coact with the edges of the recess 4. The second concave member 6 is disposed upon the lower face of the plate, and it fits upon the outside of the small sides 3. The members 5 and 6 are pierced with central holes for the inthe nut 11 may be turned to hold the device together.

Obviously, the large panels are secured together at their junction points, as specified in the aforesaid patent.

I claim:

1. A flooring comprising a panel made up of a plurality of similar units secured each to each at their meeting corners by tubular connectors for introducing a binding medium therethrough, substantially as and for the purposes set forth.

2. The method of laying flooring which consists in assembling a plurality of units into panel formation, connecting the corners of'said units each to each by a tubular connector, laying the panel on the supporting floor, and passing a binding medium through said tubular connector, substantially as described and for the purposes set forth.

3. A flooring comprising panel members made up of a plurality of similarly shaped metallic plates connected each to each by vertical tubular connectors for introducing a binding medium therethrough, substantially as and for the purpose described.

4. In a metallic flooring for factories, pressed metal plates of square form provided with four small sides. at the corners completing an octagonal form, a downward flange on the edges of the metal plates and recesses on the surface of the plates in front of the small sides, an upper concave member of square form fitting into the recesses of four adjacent plates, an under concave member underneath engaging the flanges of the same adjacent plates, and tubular means through which a binding may be passed for clamping together the two concave members.

5. In a metallic flooring for factories as claimed in claim 4:, pressed metal plates of square formprovided with four small sides at the corners completing an octagonal form, a downward flange on the edges of the metal plates and recesses on the surface of the plates in front of the small sides, an upper concave member of square form fitting into the recesses of four adjacent plates, an under concave member underneath engaging the flanges of the same adjacent plates, downturned tongues .centrally provided in the under concave member, and a tubular fa tening device through which a binding may be passed clamping together the two concave 1 members the head of which is inserted between the downturned tongues. In testimony. whereof he has signed this specification.
